Error message

[claude_agent_sdk] subprocess timed out while waiting for exit

What it means

The claude_agent_sdk subprocess did not exit within the 30-second wait timeout after output reading completed — the process is hung. The sibling read path kills the child on timeout; this site surfaces the hang as an error so the caller's turn fails fast instead of blocking the task indefinitely.

Solutions

1. Treat the turn as failed and retry
2. Check for a stuck claude subprocess and kill it
3. Investigate CLI hangs (interactive prompt, blocked I/O) if recurrent

When it happens

Trigger: Thrown at src/openhuman/inference/provider/claude_agent_sdk/subprocess.rs:221 when the library encounters an invalid state.

Common situations: See trigger scenarios.
